Really? Not noticeable in the car? Cool. My aftermarket cat back Vorsteiner set up added some volume and I am really hesitant to make it any louder. The sound quality was really improved for me but I am definitely concerned about doing something that will make long freeway trips and road trips annoying to unbearable.
